I forgot to try RTL 234 but that was audible (weak) in the early evening.

The Tecsun PL-390 was used with its internal ferrite rod antenna. The PL-390 is a terrible longwave radio but it still tried DXing, and managed to get RTÉ on 252 kHz. 'fmdxklaas' in Lelystad has received Irish radio (along with BBC Radio Scotland from Oban on 93.3) via SpE, which shows that Ireland is serious distance, especially here in the city centre. The G5 is my best LW radio but the LW and MW don't work anymore as the piece of wire between the ferrite rod aerial and the AM section snapped when fitting the new narrow filters for FM. RTÉ reception in rural Holland may be better as there is lots of EMI in my apartment.

I'm afraid that there aren't many pirates in coastal Holland, they usually come from Overijssel, Friesland and Drenthe, two of which are inland provinces of the Netherlands near the German border. I forgot to try them as my PL-390 only tunes up to 1710 kHz when it is in American mode (10 kHz steps), whereas it was in European mode (9 kHz steps) when I was in Holland.
The Ford Focus (Mk. III) car radio does tune the X-band, but it is an Easter egg as when it is tuned to any frequency between 1621 and 1710 kHz, it shows the incorrect frequency '1620 kHz' for some bizarre reason. In my opinion, I think that a radio should either have the X-band or not, instead of being able to tune the X-band with the frequency displayed as '1620 kHz' so one doesn't know what frequency they are tuned to!
At night-time in East Harling, I remember a Dutch pirate on the X-band playing the Soft Cell song 'Tainted Love', then I heard a Dutch-speaking DJ so I knew it was Dutch. There was also one on 1512 kHz that I heard on the A11 heading home from Norwich one day, which played a mixture of Dutch folk music and English-speaking middle-of-the-road music, again with one of those typical Dutch pirate DJs.
Even on a motorway in Overijssel, I have never heard any pirates on FM, even on their typical frequencies like 94.5, 97.3 or 97.0, even though I have heard a very weak Dutch pirate on 108.0 at home which could've been Woudster from Jubbega, Friesland. That was in a good tropo.
